just cleaned my starite/pentair de filter. it takes 7.2 lbs of new DE media. Just curious here, there is 48 sqft of filter screen to cover, how can you be sure that the filter is covered evenly. I mix with water from pool first, then into skimmer with pump running fast, so how do i know the DE stuff doesn't hit the bottom half of the filter, and stay there, instead of going all over the filter. From cleaning before, seems like it is spread out, but it also seems thicker on some parts of the filter, than other parts. Could it be that it falls off when I open up the case to clean it off.
